CVE-2018-1268
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCloud Foundry Loggregator, versions 89.x prior to 89.5 or 96.x prior to 96.1 or 99.x prior to 99.1 or 101.x prior to 101.9 or 102.x prior to 102.2, does not validate app GUID structure in requests. A remote authenticated malicious user knowing the GUID of an app may construct malicious requests to read from or write to the logs of that app.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Loggregator component in Cloud Foundry fails to validate that the requesting user is authorized to access logs for a specific app GUID. An authenticated attacker who knows an app's GUID can bypass authorization checks to read or write logs for any application in the foundation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Loggregator component versionRun 'bosh -d <deployment-name> vms' to list VMs, then 'bosh -d <deployment-name> ssh loggregator/0 -c "cat /var/vcap/packages/loggregator release/version"' or check the BOSH release manifest for the Loggregator release versionAffected if The installed Loggregator version falls within any of these ranges: >=89 and <89.5, >=96 and <96.1, >=99 and <99.1, >=101 and <101.9, >=102 and <102.2
-
Verify Loggregator API endpoint accessibilityCheck if the loggregator API endpoint (typically at /doppler.io.something or the logs endpoint) is exposed and accessible to authenticated users in your Cloud Foundry foundationAffected if Loggregator API is accessible to users who should not have access to logs for arbitrary app GUIDs
-
Review Loggregator audit logs for anomalous accessSearch Loggregator or Doppler logs for requests where the user identity does not match the app GUID being requested, or for unusual access patterns to apps the user does not ownAffected if Logs show any access to app logs where the requesting user is not authorized for that specific app GUID (indicating active exploitation or misconfiguration)
You are affected if your deployed Loggregator version is one of the vulnerable versions listed and users can access logs for apps they do not own by knowing the app GUID.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data89.596.199.1
Upgrade Loggregator to version 89.5, 96.1, 99.1, 101.9, 102.2 or later. Implement additional logging and monitoring for anomalous log access patterns to detect potential exploitation.
